This is too true, but its more greed than anything else now days. I have been in contact with a lady at the Centre for Environment Studies to do some photographic research in an area that has a healthy population of bullfrogs (thanks John for that link to her website) and they are concerned about the area next to the water pan being developed for what is known as low cost housing. Due to apartheid in South Africa we have a large portion of our population that is previously disadvantaged so as a governemnt project they build low cost housing for these people (wont get into the politics here) but these houses tend to get built in areas where there is peranial water holes (surely can't be very stable) but at the cost of many indigineous species being destroyed. The only way to prevent this from happening is to prove that a threatened species inhabits this area which is what she is doing. So hopefully with my photographic research I will be able to give them a helping hand in recording numbers and preventing this from happening.
